Supplementary dataset for the paper: The “Trojan horse” strategy: seed fungal endophyte symbiosis helps to explain the invasion success of the grass Poa annua in Maritime Antarctica Aim: Poa annua L. (annual bluegrass) is presently the sole invasive vascular plant species to have successfully established in Maritime Antarctica, where it poses a significant conservation threat to native plant species. However, the reasons for its success in the region have yet to be established. Here, we determined whether the invasiveness of P. annua , and its competitiveness with the native Antarctic hairgrass Deschampsia antarctica , is influenced by symbioses formed with seed fungal endophytes, and whether plants derived from seeds from four global regions differ in their performance. Locations: Four regions (Maritime Antarctica, sub-Antarctica, South America and Europe). Methods: Endophyte frequency was measured in P. annua seeds collected from the four regions. The germination, survival, biomass accumulation, flowering ...
